docs(epiphany): cross-ref OGAR#62 ProjectActor in SMOKE-4 entry

OGAR#62 merged 2026-06-19T12:00:45Z (project_actor at CODEBOOK 0x0004).
Collapses Redmine+OpenProject User/Principal/ApplicationRecord STI
chain (4 source classes → one canonical), proving binary cross-curator
convergence on real Rails sources.

Updated SMOKE-4 entry's Cross-repo alignment paragraph to include #62
alongside #61. OGAR's project-management quartet (project,
project_work_item, billable_work_entry, project_actor) is
complementary to this commit's commerce/billing/erp sextet
(CommercialLineItem, CommercialDocument, TaxPolicy, BillingParty,
PaymentRecord, CurrencyPolicy). Different domain, same promotion
mechanics.

The STI-collapse pattern OGAR#62 demonstrated for ProjectActor is the
same shape my BillingParty lexical detector applies on
OSB::Client + Odoo::res_partner — same mechanism, different domain.

 **Scope discipline (carried).** Lexical class-shape is the minimal viable detector. Structural-shape refinement (incoming OGIT canonical relations FROM line-items for TaxPolicy; outgoing has_many to line-items for CommercialDocument; etc.) is the natural follow-up. Each concept promotion is one named test on real data, not a class hierarchy hand-built up-front. The `CanonicalConcept` enum still doesn't include SalesOrder / SalesOrderLine / ProductOffering / FulfillmentFlow / InventoryMovement / ProjectWorkItem / BillableWorkEntry — those land when ≥2-curator evidence appears (operator smoke target B needs a Spree harvest; smoke target C needs Project::TimeEntry + materialization rules).
 
-**Cross-repo alignment with `AdaWorldAPI/OGAR#61`.** The merged `OGAR#61` introduced the `const CODEBOOK: &[(&str, u16)]` registry minting stable `u16` ClassIds for promoted canonical concepts (today: `project`, `project_work_item`, `billable_work_entry`). The ar_shape `CanonicalConcept` enum is the UPSTREAM candidate set — concepts get promoted into OGAR's CODEBOOK once they've cleared the ≥2-curator gate AND the OGAR-side review. Each `CanonicalConcept::CommercialLineItem`/`CommercialDocument`/`TaxPolicy`/`BillingParty`/`PaymentRecord`/`CurrencyPolicy` is a candidate row for a future OGAR CODEBOOK assignment.

The ar_shape `CanonicalConcept` enum is the UPSTREAM candidate set — concepts get promoted into OGAR's CODEBOOK once they've cleared the ≥2-curator gate AND the OGAR-side review. Each of this commit's `CanonicalConcept::{CommercialLineItem, CommercialDocument, TaxPolicy, BillingParty, PaymentRecord, CurrencyPolicy}` is a candidate row for a future OGAR CODEBOOK assignment (commerce / billing / erp domain, complementary to OGAR's existing project-management quartet). The STI-collapse pattern OGAR#62 demonstrated for `ProjectActor` is the same shape my `BillingParty` lexical detector applies on OSB::Client + Odoo::res_partner — same mechanism, different domain.
